  23. 23. Measures to promote River Restoration in Asia Background surrounds River Restoration River restoration is a new technology compared with flood control and water utilization. Applicable technologies are required based on accumulated experiences and knowledge. Asia Monsoon region has specific characteristics. Extensive variation of seasonal rainfall or discharge Growth of rice cultivation on river plains Various organisms in paddy fields Rapid concentration of the population into urban areas Discussion between countries/regions in similar geological and meteorological condition will provide more improved technology for rich river environment restoration.
  24. 24. Measures to promote River Restoration in Asia Summary of Discussion in the Session on WWF4River restoration is of vital importance to socio-economic sustainabledevelopment in parallel with flood and water use management.Basin is a basic unit for river environment management.Establishing suitable methodological technology for river restoration thatsuit for Asian monsoon region is necessary.In Asia monsoon region, human-influence to a cultural landscape isharmonized with the ecosystem traditionally.It is important to develop a database of projects and knowledge ofinternational experts in river restoration, and this activity should besupported by engineers, scientists, ecologists, managers and public.It is urgent to establish a river restoration guideline suitable for the Asianmonsoon region for countries with similar social and natural conditions.
